Abstract

With the increasing global energy demand and enhanced environmental protection awareness, the proportion of new energy power generation systems in electricity supply has gradually increased. However, the intermittency and volatility of these systems pose challenges to the stable operation of power grids, making energy storage technology crucial for addressing this issue. This study aims to explore energy storage technologies suitable for new energy power generation systems by comparing and analyzing the characteristics, costs, and application scenarios of different storage methods. A hybrid energy storage system model based on lithium-ion batteries and supercapacitors was constructed using practical case studies. The model was tested and validated through simulation software, evaluating system performance under various operating conditions. Results indicate that the hybrid storage system can effectively mitigate power fluctuations from new energy generation, improve power quality, and extend equipment lifespan. An innovative control strategy was proposed to achieve complementary advantages between the two storage devices, enhancing overall system efficiency and reliability. This research provides new insights into the optimal configuration of new energy power generation systems and holds significant implications for promoting large-scale applications of clean energy.
